Brussels in March — Full Picture
March in Brussels is the start of spring — milder, brighter, and longer-dayed than winter, though still cool and prone to rain. It averages 11°C/3°C with 65mm of rain.
The city begins to wake up: outdoor café terraces reappear on warmer days, and parks like the Bois de la Cambre and the Parc du Cinquantenaire show the first green. It's a pleasant shoulder season with moderate crowds and prices.
If Carnival dates fall late, the Binche Carnival can land in early March — worth checking. Easter, which moves each year, sometimes falls in March and brings a small bump in visitors and chocolate displays (a big deal in Belgium).
Clocks go forward to summer time late in the month, stretching the evenings and lifting the mood. Skies are still changeable, so keep a rain jacket, but the worst of winter's gloom is easing.
Note: it can still feel cold, especially mornings and evenings — dress in layers and don't pack away the warm coat yet.
What to Wear & What to Pack
Early spring — around 11°C/3°C with a big day-night swing. A coat or warm jacket, layers, and a light scarf, plus a rain jacket. Cool mornings warm a little by afternoon.
